In a study published today in Lancet Child and Adolescent Health, researchers at King's College London looked at daily health reports logged in the ZOE COVID Symptom Study app between March 2020 and February 2021 by parents or carers on behalf of more than 250,000 children aged 517, with nearly 7,000 having symptoms consistent with COVID19 and a positive test.
The team previously analysed data from adults using the ZOE COVID Symptom Study, and showed that around one in 7 adults experienced COVID-19 symptoms lasting 4 weeks, while one in 20 were ill for 8 weeks or longer.
For this analysis, the team focused on the period from September 2020 through to February 2021. This coincided with the reopening of schools in the autumn and the peak of the winter wave when there was widespread availability of COVID testing.
